JUDAI-I TOURO ROBERTSON, OF NEV YORK, N. Y.

SAFETY-PAPER.

SPECIFICATION forming part of Letters Patent No. 538,625, dated April30, 1895. Application filed March 9. 1894. Serial No. 503,002. (Nospecimens.)

To @ZZ whom, it may concern:

Be it known that I, JUDAH ToURo ROBERT- SON, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, haveinvented certain new and useful Improvements in Safety-Paper;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to certain improvements in what has been termedprotective, safety or distinctive paper designed to be used for checks,notes, bonds or other securities.

The object of the invention is to produce a paper printed, or otherwiseimpressed,with various colors, which, when written upon, the writingcannot be erased or altered without removing one or more of the colorsand which removed color or colors cannot be replaced to conform to theoriginal. To accomplish this object I print, or otherwise impress, uponthe paper on different parts of its surface one or more deleble and oneor more fast colors. These are either printed with strict lines ofregistry or the deleble and fast colors slightly blending or lapped asin chromatic printing. Should writing upon the paper so prepared beerased, such, for instance, as in raising a check, it would be almost ifnot impossible to match the lines of the work in endeavoring to restorethe tint originally used, more particularly where the lines arecontinuous in different colors.

The invention above referred to will be fully hereinafter described andpointed out in the specification and claims, reference being had to thedrawing, in which the fast and deleble colors are simply illustrated asprinted alternately.

' In manufacturing my improved paper I print, or otherwise impress, uponthe same a fast and a deleble color either arranged alternately, asshown in the drawing, or upon different portions of said paper, theletter A representing the fast color, the letter B the deleble color.These fast and deleble colors are ordinarily printed or impressed uponthe paper, so that the lines register strictly, but may be printed toslightly overlap or blend. Should an attempt be made to remove or alt-erany writing upon the paper so prepared, the deleble color would beremoved at such' places upon said paper where there was a deleble color.To restore this color with the exact tint, and to match the linesbetween said deleble and fast colors, could not be done'in such a manneras to deceive, especially where the lines are continuous for deleble andfast colors in juxtaposition. v

Having thus fully described my invention, what I claim is` l. A paper orother article printed, impressed or colored on different parts of itssurface with one or more fast and one or more deleble colors, formingcontinuous regular or irregular lines, at the dividing lines of the fastand deleble colors, substantially as shown and described, for thepurpose specified.

2. A paper or other article printed or otherwise overlaid on its surfacewith one or more deleble and one or more fast inks forming specicdividing lines between the fast and deleble inks on said surface,substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.n
